Product detail

The DNT Hydra HS635 is equipped with a 12μm ≤18mk thermal 640x512 pixels sensor for ultra-clear thermal images, and DNT's proprietary Super Resolution image algorithm just made the impossible, possible.

This amazing technology now enhances your thermal image to the next level and resolves the biggest issue of thermal losing definition after digitally zooming in.

Notably, its 1.5-6x(1.5x,2.25x,3x,4.5x,6x) continuous digital zoom captures fine details in total darkness, ideal for nocturnal hunting and surveillance.

Engineered with magnesium alloy housing, this scope withstands extreme weather (-20°C to 50°C), while its IP67 rating ensures reliable performance in rain, fog, or dust.

Buyer guidance

Choose it for the right job

Plain, practical checks for UK buyers comparing thermal, night vision and rifle optics before paying.

Close pest control

Rats around buildings or feeders are usually short range. Prioritise a clear image, quick start-up and easy handheld handling before chasing maximum distance.

Rabbit and fox work

For rabbits and foxes, check realistic identification distance, LRF needs and battery life. A higher sensor and suitable lens matter more than bold marketing range claims.

Mounting check

If it is going on a rifle, confirm the tube, mount or rail fit before payment. Common checks include 30 mm / 34 mm rings, Picatinny or dovetail fittings and eye relief.

Compatibility checklist

Useful details to confirm before payment, especially for rifle-mounted optics and add-ons.

  • Intended use: rats, rabbits, foxes, target shooting or observation
  • Typical distance: under 50 m, 50-150 m, 150-300 m or longer fields
  • Mounting: 30 mm / 34 mm tube, Picatinny, Weaver, dovetail, clip-on or handheld
  • Accessories: IR illuminator, battery pack, charger, rail, case or tripod
